How to find part number?

[Will.iam]

My A&P doesn’t have a tsio-360-mb service manual only a KB. Where do i go to get a current parts manual and does that parts manual have part numbers referenced to them? If not what manual is that that i need to get? He is trying to reinstall my throttle body but needs a new gasket. I’m trying to get the part number for him but can’t seem to find it. Although the attached picture shows very well which gasket part i need (item 22) it does not show me a part number so he could order it. Please help. A part number would be great to go get it before the weekend from a local shop but if somebody can tell me where i can purchase a parts manual for tsio-360mb i could find these things in the future. Thanks.

The IPC from Continental is what I usually use.

Thanks. I called continental and was ready to purchase a subscription so i could access the parts manual but the nice lady explained I didn’t need to do that if i was only looking for a part number and knew what part it was. So she showed me their online parts manual that is free I couldn’t believe that but i got the part number and it will be ready for pickup this afternoon. Hopefully my A&P can get it fixed this evening.
